We have a 2014 Shockwave. We like it, but we have had a couple of issues that needed warranty work. The most annoying one was that the leveling jacks were only put on with these small self-tapping screws. The Wood Village Camping World actually stepped up for us on this one and fought with FR on my behalf to put actual bolts on. An overhead panel scratch in the bedroom and non-working USB charge ports were the only other issues (both fixed). I haven't had any complaints since those have been fixed over a year and a half ago.
I did have a generator fire while I was doing the monthly run. Carburetor on the Onan 4k was leaking fuel. I saw the fire right away. Put it out before it did any damage. Just melted some wire covers. There's a good reason to start your generator locally instead of remotely.
The good things are how well insulated it is, how well it tows, and how much room it has (toy hauler) even without a slide out.
